Stacking-order-dependent electronic properties of MoTe2/WSe2 moiré bilayers
Zhongdong Han, Wenjin Zhao, Eegene Clara Chung +17
Transition metal dichalcogenide (TMD) moiré bilayers have realized a wide range of strongly correlated and topological phenomena. The physics in these materials is often sensitive…
Emergence of a symmetry-broken Chern insulator near a moiré Kondo breakdown
Wanghao Tian, Bowen Shen, Lizhong Li +14
Moiré semiconductors built on angle-aligned transition metal dichalcogenide (TMD) heterobilayers provide a physical realization of the Kondo lattice model, in which one TMD layer…
Electric-field-tuned consecutive topological phase transitions between distinct correlated insulators in moire MoTe2/WSe2 heterobilayer
Xumin Chang, Zui Tao, Bowen Shen +10
Consecutive topological phase transitions (TPTs) between strongly correlated electronic phases that differ simultaneously in symmetry breaking and topological order are of fundamen…
Emergence of Chern metal in a moiré Kondo lattice
Wenjin Zhao, Zui Tao, Yichi Zhang +9
A Chern metal is a two-dimensional metallic state of matter carrying chiral edge states. It can emerge as a doped Chern insulator, but theoretical studies have also predicted its e…
Controlling Schwinger tunneling via engineering of virtual particle phases in vacuum
D. D. Su, B. F. Shen, Q. Z. Lv
An investigation into Schwinger pair production mechanisms is presented, demonstrating that vacuum tunneling processes can be effectively controlled through electromagnetic potenti…
Time-reversal symmetry breaking fractional quantum spin Hall insulator in moiré MoTe2
Kaifei Kang, Yichen Qiu, Bowen Shen +7
Twisted bilayer transition metal dichalcogenide semiconductors, which support flat Chern bands with enhanced interaction effects, realize a platform for fractional Chern insulators…
